The PTP540 is a MOSFET TO-220 RoHS-compliant power transistor manufactured by PIP. It is a N-channel enhancement-mode horizontal-structure vertical DMOS FET that is commonly used in power converters, DC/DC converters, and automotive applications. The PTP540 is designed for output applications with its on-state resistance being adjustable with gate voltage between 0.12ohm and 0.35ohm. It has an intrinsic fast switching speed, offering fast switching times, low capacitances, and low Rds(on). The PTP540 is also RoHS compliant, making it a great choice for applications that need to meet strict environmental standards.
